This morning, the Federal Circuit released one precedential opinion and five nonprecedential opinions. In the precedential opinion, the court reversed a decision of the Patent Trial and Appeal Board based on an incorrect interpretation of the patent statute in the context of determining what qualifies as prior art for use in an inter partes review proceeding. Of the nonprecedential opinions, one comes in a vaccine case, one in an international trade case, one in a patent case appealed from the Patent Trial and Appeal Board, and two in patent cases appealed from district courts. Notably, Judge Stark filed additional views in the international trade case, indicating potential disagreement with the court’s law governing differential pricing analyses, while Judge Prost filed a concurring opinion in the nonprecedential opinion reviewing a decision of the Patent Trial and Appeal Board. Here are the introductions to the opinions.
